J.Lo and Cameron are filming a movie together and "the tension is thick." Gerard Depardieu explains why he peed in an airplane's aisle. Jesse James and Kat Von D are back together. Leo and Blake are shopping for a house. TGIFriday gossip.

Jennifer Lopez and Cameron Diaz are co-starring in What to Expect When You're Expecting and "the tension is thick" because Cam supposedly thinks J.Lo's personal drama and tabloid jockeying are "a distraction from work." Cam is "also annoyed by Jennifer's huge entourage, which includes her mom, three assistants, makeup and hair people and her manager. She made a snide comment to the effect of, 'How many people does it take for one woman to film a simple scene?'" That's it? Fame-whoring, awkward silences, and the presence of a mom? There was a time when a decent J.Lo diva story required 20 mirrors, 50 stylists, physical violence, and royals in peril. I demand more from my J.Lo diva stories. Apparently Jennifer "doesn't talk about Cam or ask about her. She just acts as if Cam doesn't exist." Though ignorance is a powerful weapon in the hands of the haughty, I'm giving this story a low 2 on the J.Lo Diva Meter. [Celebitchy, images via Getty]

Gerard Depardieu's excuse for peeing in the aisle of an airplane: He "offered to clean up the mess," was "stone-cold sober," and "has prostate problems and it was very worrying and humiliating for him." The man who stood up mid-tantrum, whipped out his dick, and peed on the floor says he is the victim here. That said, prostate problems do sound like a bitch. [TMZ]

Bad ex-boyfriend reality star Jesse James is back together with painted lady reality star Kat Von D after a month-long hiatus from their engagement. They announced it with matching lovey-dovey Twitter pictures, on the day Kat's show got cancelled. [People, @FreeJesseJames, TheKatVonD]

Would you like a glimpse "Inside Kim Kardashian's 3-Hour Wedding Rehearsal Dinner," in preparation for tomorrow's wedding? Not really? Then don't click this link. [Us]

Speaking of Kim's wedding (I know, I know, but it'll be unavoidable for the next 24 hours) Donald Trump is skipping it to go golfing. (At his own golf tournament. But still!) Meanwhile, wedding security will be "tighter than Bruce Jenner's face," "as if it was the White House," so maybe the Salahis wander in and take Donald Trump's place? [P6,TMZ]

Emilio Estevez says brother Charlie Sheen is a changed man: "He's a completely different guy. He's got his voice back. And I think he's got his focus." Also, he could beat Charlie up if they ever got in a fight. No, seriously, that is what the interviewer asked next. [AccessHollywood]

Sandra Bullock and Ryan Reynolds went hiking together, and Ryan wore the baby backpack thing-a-ma-jig that Sandy's baby rode in, so they are definitely in love and committed, because you don't strap your baby to just anyone's back, y'know? When you trust a man enough to tie an infant to his back, that is love. [TMZ]

Another day, another Foxy Brown diva freak-out at a random restaurant in Prospect Heights. Someone should make the Foxy Brown Diva Freak-Out Tour of Forgotten Neighborhoods in Brooklyn, a progressive dinner featuring historical reenactments of eye-clawing catfights and pleasant hors d'oeuvres. A good use for Brooklyn's surplus actor/singer/songwriter/model/waiters. [P6]

Anthony Bourdain says fellow TV chef Paula Deen is the "most dangerous person in America" because she uses too much butter when she cooks. God, when did dangerous Americans become so lame? In the old days, serial killers were flaying women alive and fashioning outfits out of their skin, not feeding them cupcakes. Anyway, here's the Sparkly-Eyed Granny of Death's response: "Anthony Bourdain needs to get a life." Dangerous Americans are really under delivering these days. [P6]

Leonardo DiCaprio and Blake Lively might be house-hunting in New York together, even though Leo might have almost dumped her for "getting too clingy" a month ago. Blake Lively might be a unicorn princess sent from planet Sparkle Cleavage to save the children of Earth, but I'm not sure yet, so let's just say "allegedly" and call it a day. [Celebitchy]
